When equipment starts up, temporary power surges are normal—but that doesn’t mean your protection device should trip every time a motor kicks on. That’s where the TR40R shines. This 40 Amp time-delay fuse is designed to handle inrush currents while still delivering fast, dependable protection against overloads and short circuits. Its current-limiting Class R construction helps reduce potential damage during fault conditions, making it a smart choice for commercial and industrial applications where protecting valuable equipment is a priority. With a high 200 kA interrupting rating at 250V AC, the TR40R delivers the confidence that electricians, maintenance teams, and facility operators look for in demanding environments.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features and Benefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e40 Amp Protection:\u003c\/strong\u003e Provides dependable protection for commercial and industrial electrical systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTime-Delay Performance:\u003c\/strong\u003e Helps prevent nuisance fuse openings during motor startup and temporary surges.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent-Limiting Class R Design:\u003c\/strong\u003e Helps reduce damage caused by high fault currents.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh Interrupting Capacity:\u003c\/strong\u003e 200 kA interrupting capacity at 250V AC supports high-performance protection requirements.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCartridge-Style Construction:\u003c\/strong\u003e Allows for simple installation and replacement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNon-Indicating Design:\u003c\/strong\u003e Suitable for a wide variety of circuit protection applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact Size:\u003c\/strong\u003e Makes it easier to fit into crowded panels and electrical assemblies.\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e TR40R\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuse Type:\u003c\/strong\u003e TR\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e 40A\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage Rating:\u003c\/strong\u003e 250V AC\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA.I.C.
